Down lighters on photocell and PIR

[DanL]

A friend has asked its possible to put 3 spots in a bulkhead outside his house so they're dim between dusk and dawn then turn on full when movement is detected through a PIR. I've searched for a dimmable photocell but haven't had any joy. The spots will obviously be IP65 and will be LED, again obviously with dimmable lamps.
Any in depth solutions will be much appreciated

Photocell and dimmer in series with a PIR in parallel would do it.

Top stuff! Cheers. This is the way we were going to try to start with

Seems it has been tried as an app? I don't really understand what they are talking about lol but can see the concept!
